Description

一种基于TPB和多羧酸配体的发光金属-有机框架材料及其制 备方法和应用
技术领域
本发明属于发光晶体材料技术领域,具体涉及一种基于TPB和多羧酸配体的发光金属-有机框架材料及其制备方法和应用。
背景技术
现代工业的蓬勃发展提高了我们的物质生活,同时也带来了严重的环境污染。作为重要的基础工业原料,例如,硝基芳环爆炸物,包括2-硝基苯酚(2-NP),4-硝基苯酚(4-NP),2,4-二硝基苯酚(2,4-DNP)和2,4,6-三硝基苯酚(TNP)已被广泛用于生产染料,农药,药物,炸药等。但是,这些芳香族硝基化合物具有高毒性而且难以降解。因此引起了严重的健康和环境问题。所以爆炸性分子的快速,便捷和选择性检测非常重要。
近年来,发光金属-有机框架材料(LMOFs)由于检测灵敏度高、响应时间快、可操作性强等优点,在pH检测、离子传感、挥发性有机化合物的传感、硝基爆炸物检测等领域引起广泛的研究。有机配体是具有发光性能的金属-有机框架的基本组成成分。有机配体的发光即可导致金属-有机框架材料(MOFs)的发光。所以,有机配体的选择/设计是获得LMOFs的关键方法。在以往的研究中表明含N的芳香族的配体具有一定的发光特性。多齿的含N配体可以提供多个不同的配位点,从而导致不同的配位方式并产生不同结构的MOFs。而且多齿配体不仅可以增强MOFs的化学稳定性还可以增强MOFs的刚性。除了多齿含N配体外,芳香族羧酸配体不仅具有多种结合模式,从单齿到多齿(二桥,三桥和四桥等),也可以表现为良好的氢键受体和给体,从而提供了金属-有机框架材料结构的稳定性。
目前,有不少技术手段可用于芳香硝基化合物(NACs)的检测,例如,气相色谱-质谱连用、拉曼光谱、中子活化分析、热氧化还原法。但是这些方法都需要大型的仪器设备,成本较高,而且样品的预处理程序也较为复杂,不适合普遍使用和对污染物的实时监控。
发明内容
针对现有技术的不足,本发明提供一种基于TPB和多羧酸配体的发光金属-有机框架材料及其制备方法和应用,对芳香硝基爆炸物2,4,6-三硝基苯酚(TNP)具有高灵敏的探测性能。

步骤2)将反应釜放在100℃的烘箱中恒温反应72h,以2℃/h的降温速率降温至室温,得到透明块状晶体即为所述基于TPB和多羧酸配体的发光金属-有机框架材料,其分子式为C18H10N2O4Zn。
